water-filled bamboo tube that clacks against a stone when emptied; traditional Japanese garden water feature
A traditional Japanese garden device: a bamboo tube that slowly fills with water, tips, and strikes a stone with a sharp clack. Also known as ししおどし (deer scarer), though 添水 specifically refers to the water-filled tube mechanism.
Hearing the sound of the 添水 in a Japanese garden is calming.
